note 82164 added to function.ereg

I noticed that /s which is used to check for spaces doesn't work with ereg. Not sure why. Here's an example of a US phone validation function that works for me. I couldn't find a working example anywhere, so here it is. <? function invalid_phone($phone_no){ $pattern = "^(\()?([0-9]{3})(\))?( )?([0-9]{3})( )?(\-)?( )?([0-9]{4})$"; $phone_no = trim($phone_no); if (!ereg($pattern, $phone_no)) return 1; return 0; } // invalid_phone // example of use $phone = "(503) 555-1212"; // ok $phone = "(503) 555 - 1212"; // ok $phone = "503-555-1212"; // ok $phone = "503 - 555 - 1212"; // ok $phone = 5035551212; // ok if (invalid_phone($phone) > 0) echo "Make sure the phone number you have entered matches the standard format: (503) 555-1212"; ?> ---- Server IP: 209.41.74.194 Probable Submitter: 70.192.119.150 ---- Manual Page -- http://www.php.net/manual/en/function.ereg.php Edit -- https://master.php.net/note/edit/82164 Del: integrated -- https://master.php.net/note/delete/82164/integrated Del: useless -- https://master.php.net/note/delete/82164/useless Del: bad code -- https://master.php.net/note/delete/82164/bad+code Del: spam -- https://master.php.net/note/delete/82164/spam Del: non-english -- https://master.php.net/note/delete/82164/non-english Del: in docs -- https://master.php.net/note/delete/82164/in+docs Del: other reasons-- https://master.php.net/note/delete/82164 Reject -- https://master.php.net/note/reject/82164 Search -- https://master.php.net/manage/user-notes.php
